Question: 1 / 400

What is the definition of flexion in a medical context?

Extension of a joint

Opening of a joint

Closing of a joint

Flexion in a medical context refers specifically to the action of decreasing the angle between two parts of the body, typically at a joint. This movement effectively "closes" the joint, bringing the two segments closer together. For instance, when you bend your elbow, you are performing flexion, as the angle between the forearm and the upper arm decreases.

This movement is essential in many bodily functions, such as walking, reaching, and lifting. Understanding the concept of flexion is important in fields like physical therapy and rehabilitation, where restoring and improving joint movement is a primary focus. This basic definition of flexion contrasts with other movements like extension, which increases the angle between body parts, or rotation, which involves turning around an axis. These distinctions clarify why the described action of "closing" a joint defines flexion accurately.
